Creating a Search Box in React JS | Updated 2024

66

In contemporary web development, integrating a search box is a frequent necessity for diverse applications. React.js, a leading JavaScript library for constructing user interfaces, offers multiple methods to implement a search box efficiently. This comprehensive guide will walk you through the process of building a search box in a React.js application, covering basic input fields, autocomplete functionality, debouncing for performance, integration with external APIs, and customization.

Guiding Steps for Search Box in React JS with Example 

Step 1: Setting Up the Basic Search Input Component

• Create a new React component for the search box.
• Render a simple input field for users to enter search queries.
• Set up state management to store the search query entered by the user.

import React, { useState } from 'react';

function SearchBox() {
  const [query, setQuery] = useState('');

  const handleChange = (event) => {
    setQuery(event.target.value);
  };

  return (
    <input type="text" value={query} onChange={handleChange} placeholder="Search..." />
  );
}

export default SearchBox;

Step 2: Adding Autocomplete Functionality

• Integrate an autocomplete feature using a library like React Autosuggest.
• Configure the autocomplete component to fetch suggestions from an API.
• Implement logic to update the suggestions dynamically as the user types.

import React, { useState } from 'react';
import Autosuggest from 'react-autosuggest';

function SearchBox() {
  const [query, setQuery] = useState('');
  const [suggestions, setSuggestions] = useState([]);

  const getSuggestions = async (value) => {
    // Fetch suggestions from an API based on the input value
    // Update the suggestions state with the fetched data
  };

  const handleChange = (event, { newValue }) => {
    setQuery(newValue);
  };

  const onSuggestionsFetchRequested = ({ value }) => {
    getSuggestions(value);
  };

  const onSuggestionsClearRequested = () => {
    setSuggestions([]);
  };

  const renderSuggestion = (suggestion) => (
    <div>
      {suggestion.name}
    </div>
  );

  const inputProps = {
    placeholder: 'Search...',
    value: query,
    onChange: handleChange
  };

  return (
    <Autosuggest
      suggestions={suggestions}
      onSuggestionsFetchRequested={onSuggestionsFetchRequested}
      onSuggestionsClearRequested={onSuggestionsClearRequested}
      getSuggestionValue={(suggestion) => suggestion.name}
      renderSuggestion={renderSuggestion}
      inputProps={inputProps}
    />
  );
}

export default SearchBox;

Step 3: Implementing Debouncing for Enhanced Performance

• Enhance the search box with debouncing to reduce unnecessary API requests.
• Utilize a debouncing library like Lodash to delay API requests.
• Optimize the debounce delay for responsiveness and performance.

import React, { useState } from 'react';
import { debounce } from 'lodash';

function SearchBox() {
  const [query, setQuery] = useState('');

  // Debounce the handleChange function to delay API requests
  const debouncedHandleChange = debounce((value) => {
    // Fetch suggestions from an API based on the input value
  }, 300); // Adjust the debounce delay as needed (in milliseconds)

  const handleChange = (event) => {
    const { value } = event.target;
    setQuery(value);
    debouncedHandleChange(value);
  };

  return (
    <input type="text" value={query} onChange={handleChange} placeholder="Search..." />
  );
}

export default SearchBox;

Step 4: Integrating with External APIs

• Connect the search box component to external APIs such as Google Places API.
• Implement logic to fetch search results based on the user’s input query.
• Display the retrieved search results in the UI in a user-friendly manner.

import React, { useState } from 'react';
import axios from 'axios';

function SearchBox() {
  const [query, setQuery] = useState('');
  const [results, setResults] = useState([]);

  const search = async (value) => {
    try {
      const response = await axios.get(`https://api.example.com/search?q=${value}`);
      setResults(response.data);
    } catch (error) {
      console.error('Error fetching search results:', error);
    }
  };

  const handleChange = (event) => {
    const { value } = event.target;
    setQuery(value);
    search(value);
  };

  return (
    <input type="text" value={query} onChange={handleChange} placeholder="Search..." />
  );
}

export default SearchBox;

Step 5: Styling and Customization

• Customize the appearance of the search box and autocomplete suggestions.
• Utilize CSS frameworks like Bootstrap or Material-UI for pre-designed styling components.
• Implement custom styling using CSS or CSS-in-JS libraries for finer control.

Let’s include the search-box and suggestion-item  classes:

import React from 'react';
import './SearchBox.css';

const SearchBox = () => {
  const suggestions = ['Apple', 'Banana', 'Orange', 'Pineapple'];

  const handleInputChange = (e) => {
    // Handle input change logic here
  };

  const handleSuggestionClick = (suggestion) => {
    // Handle suggestion click logic here
  };

  return (
    <div className="search-box">
      <input
        type="text"
        placeholder="Search..."
        onChange={handleInputChange}
      />
      <ul className="suggestion-list">
        {suggestions.map((suggestion, index) => (
          <li
            key={index}
            className="suggestion-item"
            onClick={() => handleSuggestionClick(suggestion)}
          >
            {suggestion}
          </li>
        ))}
      </ul>
    </div>
  );
};

export default SearchBox;

/* Example SearchBox.css */
.search-box {
  width: 100%;
}

.suggestion-item {
  padding: 10px;
  cursor: pointer;
}

.suggestion-item:hover {
  background-color: #f0f0f0;
}

How to use pop-up search box in React JS

To implement a pop-up search box in React JS. Here’s a basic example of how to achieve this:

import React, { useState } from 'react';

const PopupSearchBox = () => {
  const [isOpen, setIsOpen] = useState(false);
  const [searchQuery, setSearchQuery] = useState('');

  const togglePopup = () => {
    setIsOpen(!isOpen);
  };

  const handleInputChange = (e) => {
    setSearchQuery(e.target.value);
  };

  const handleSearch = () => {
    // Implement search functionality here
  };

  return (
    <div>
      <button onClick={togglePopup}>
        Open Search
      </button>
      {isOpen && (
        <div>
          <input
            type="text"
            placeholder="Search..."
            value={searchQuery}
            onChange={handleInputChange}
          />
          <button onClick={handleSearch}>Search</button>
          <button onClick={togglePopup}>
            Close
          </button>
        </div>
      )}
    </div>
  );
};

export default PopupSearchBox;
